Biography
Hugo de Vries was born in Haarlem, Netherlands in 1848, and he taught zoology, geology, and botany at schools in Amsterdam before becoming professor and director of Amsterdam's Botanical Institute and Garden in 1885, serving until 1918. During the 1890s, he wrote a paper on the hybridizing varieties of multiple plant species, but a friend sent him Gregor Mendel's own 50-page paper on genetics from 34 years earlier, and De Vries realized that their views were similar. Within three months, Carl Correns and Eric von Tschermak also showed the same essential work which Mendel had published. He also developed the term "mutation" and developed a mutation theory of evolution. He died in Lunteren in 1935 at the age of 87.
